I saw another post but there was more arguments then actual info. I am looking at Table R404.1.1(1) and if I am reading this correct you can go 6' stem wall with "unbalanced backfill" if you have SP SW GP or GW soils and you have 8" stem wall.
Luckily I answered my own question as the definition of "unbalanced backfill" is underneath the table and answers my question.
I am doing crawl space but I was really confused because I was tossing around the idea of doing a slab, and its confusing why you really need to be below the frost line if you have do a heated slab. I get it, frost heaving but what if you dont have a water susceptible soil.
Looks like you can "balance" your fill around your stem wall and go as high as you want without design from an engineer.
